SURFACEFINISHThe thermosetting polyester powder coating process to which PANACOR ACX160/ALX160 acoustic fence panels are subjected produces excellent resistance to the effects of adverse weather, heat or continued exposure to sunlight, by providing enhanced corrosion-resistance and thus a product that requires practically no maintenance. |
STAGE 1 PRE-TREATMENTAutomatic process to prepare panels for electrostatic application of paint powder. Dip 1 Tank capacity: 5600 l Dip temperature: 35 to 45ºC Composition of dip liquid: De-greasing agent; passivator; water; Daily monitoring of concentration levels in pre-treatment dip tank 1 according to specific procedure. Dip 2 Tank capacity: 2300 l Dip temperature: room temp. Composition of dip liquid: water Dip 3 Tank capacity: 2300 l Dip temperature: room temp. Composition of dip liquid: water |
STAGE 2 DRYINGAll metal parts are placed in a blow drying tunnel at a temperature of between 80 and 100ºC to eliminate any moisture prior to the subsequent spray coating stage. STAGE 3 PAINT BOOTHAutomatic process using robots and touch-up guns with spray nozzles that guarantee a perfectly smooth, uniform coat is applied to the panels to ensure an excellent finish. STAGE 4 POLYMERIZING OVENProcess in which the paint finish is achieved by applying heat for at least 10 minutes at an average temperature of 200 ºC Oven temperature: 165 to 230ºC. |
